Squid Poxy is blocking some web site content

I have ubuntu LTS 6.10.
Squid Version 2.5.STABLE12
All set up and working on vmware virtual machine.
Stand alone set up _that means only selected users/browser is forced
through this proxy.
Purpose of squid: Block access to all internet sites allowing only
"white listed sites"
This is all working and i'm happy with the functionality.
PROBLEM:
One program our company is using is accessing site for parts brake
down.
All works fine till you get to the point when you need to send email
out of this application.
The email is used to submit parts order or warranty claim.
trisoftinc.com is in white list and accessible
Squid access log Show series of four(4) attempts to email warranty

ITtoolbox linuxadmin-lIt would be helpful if you could provide some of your squid.conf file, but here is a stab anyway. Create ACLs
acl directaccess url_regex -i "/etc/squid/direct-access.list"
acl my_net src 192.168.1.0/24 192.168.0.0/24
then use those ACLs as below;
always_direct allow my_net directaccess (somewhere near the top of your always_direct directives)
http_access allow my_net directaccess (somewhere near the top of your http_access directives)
Now, as long as your direct-access.list file contains the FQDN or ip address of the website you should be right.
Hope this helps!

I configured this like this:
created /etc/squid/direct-access.list
trisoftinc.com209.221.150.92
(placed inside the file)
In acl with my other ones i added:
acl directaccess url_regex -i "/etc/squid/direct-access.list"
acl my_net src 192.168.10.0/255.255.255.0
http_access allow my_net directaccess(placed before http_access deny all with my other ones)
always_direct allow my_net directaccess (find always_direct in the squid.conf and added this one as the only one there)
Do i need to change permitions on the directaccess.list file?
Deny log is here:
Note that is refering to "sfs" .That is user name loged in my proxi using white list file to access the web:
